With the proprietary DOSC waveguide, the
L-Acoustics V-DOSC system was the first line
array to operate coherently across the whole
audible frequency range. Since 1993, this major
technological innovation is at the heart of every
L-Acoustics line source element, with specifically
tailored DOSC waveguides for constant curvature
arrays (ARCS systems) or variable curvature arrays
(K systems).

L-FINS

Introduced in 2008 with the KI system, the
L-Fin waveguide marked the transition from the
"V" transducer layout of legacy V-DOSC and
dV-DOSC systems to the "K" transducer layout.
L-Fins significantly improve the precision and
smoothness of the directivity pattern in the
horizontal plane. In addition to K1, L-Fins are
featured in Kara and ARCS WiFo.

ARCS WIFO

THE WORKHORSE LINE SOURCE

ARCS Wide and ARCS Focus brings the legendary sonic qualities of L-Acoustics Wavefront Sculpture Technology line sources into a compact, constant curvature enclosure, optimal for medium throw applications. ARCS WiFo is the workhorse of sound providers, going from single enclosure fill all the way up to 360° in-the-round coverage.

Because its coverage matches its shape, ARCS WiFo is easy to use, perfectly conforming to any audience configuration using few elements. ARCS WiFo combines high SPL, native low frequency performance and constant tonal balance over distance. As a standalone or distributed system, installers as well as service providers will appreciate ARCS WiFo’s performance-to-size ratio.

“Sound: Impeccable. The intention was to make Oslo the bestequipped small venue in London, and it’s been outfitted with an L-Acoustics sound system that is simply terrific. Spoon’s show there recently boasted possibly the best sound I’ve ever heard at a gig: every detail was not just audible, but crystal-clear”
